Unicode CLDR 21.0.2 is an update release, with no new translations. It contains only additional BCP47 data for the T extensions approved by the committee (see New BCP47 Extension T Fields) and a deprecation of one U extension: "direct" collation.

These new T Extension fields and subfields [RFC 6497] are now available for use in BCP47 and Unicode Locale/Language Identifiers. The CLDR committee approved new fields of the T extension for different domains, allowing users of the T extensions to ignore types of subfields that are not relevant to them, and to group related subfields in an organized fashion. The new T extension fields and subfields are defined in the following files, as part of the CLDR 21.0.2 release:
